DESCRIPTION
The GEM-HEAT is a high-quality 135°F (57°C) Fixed
temperature detector with Rate of Rise. It is compatible with the
NAPCO Express and Gemini series GEM-RECV Series
supervised security receivers..
The GEM-HEAT incorporates circuitry which will transmit an
alarm signal upon an alarm condition, generate an hourly
supervisory test signal to the receiver and also monitor and
annunciate low battery.
Coding switches are not required or used in the GEM-HEAT.
Each transmitter is assigned a unique identification code number
at the factory. The transmitter is powered by one 3 Volt Lithium
battery (supplied) which can power the unit for up to two years. If
the battery voltage drops below normal, a low-battery report will
be sent to the receiver with any status or alarm transmission. If a
low-battery condition is indicated, replace the battery.
OPERATION
Rate-of-Rise Feature:
A temperature increase of 15
0
F or
more per minute will result in an alarm transmission. When the
rate-of-rise element alone has been activated, the detector is self-
restoring.
Fixed Temperature: If the temperature of the center disk
rises to the detector’s rated temperature (135
0
F / 57°C) an alarm
transmission will result. When actuated by the fixed temperature
element, the detector is non restorable and must be replaced.
The need for replacement is indicated when the center disk has
fallen free. Order Chemetronics model 601 to replace detector.
When the GEM-HEAT detects an alarm as described above,
the integral transmitter will send an alarm signal to the receiver.
The alarm signal will be repeated every 10 seconds thereafter as
long as the alarm condition is present. A restore report will be
sent when the condition clears. Supervisory status reports are
sent from the GEM-SMK every hour.
Step 1. Remove the mounting base.
Lift the GEM-HEAT from the base by turning the heat detector
counter-clockwise while holding the base stationary.
Step 4. Mounting the base to the ceiling
Select mounting location for detector on ceiling. Do not locate
in direct path of hot or cold air flow. Remove the protective
insert from the base. Use the two screws and anchors
provided to attach the mounting plate to the wall or ceiling.
Reinstall the the protective
insert into the base.
NOTE: The mounting
plate may be attached
to a plastic single-gang
electrical outlet box.
Do not attach to
metallic outlet
boxes.
Step 3. Install the battery
Observing polarity, install the supplied Duracell DL123A
battery. Reattach the circuit board to the mounting posts using
the 4 Phillips head screws.

Step 2. Remove the circuit board
Remove the circuit board from the heat detector by removing
the 4 Phillips head screws and carefully lifting the circuit board
from the four mounting posts.
NOTE: The RF ID#
which appears on the
circuit board label
must be recorded in
order to map the
transmitter into the
system. (see Step 7).
RF ID# 7F545D5 : 7
WARNING: NOT A LIFE SAFETY DEVICE - USE FOR PROPERTY PROTECTION ONLY
NOTE: If the Auto-Enroll technique is to be
used to map the transmitter, it must be
done at the point the battery is installed.
(Consult the control panel installation
instructions for the Auto-Enroll procedure.)
NOTE:
Replace battery with Duracell
DL123A Only. Use of another battery may
present a risk of fire or explosion.
BATTERY CAUTION:
Risk of Fire, explosion and burns. Do not
recharge, disassemble, heat above 100 deg. C., or incinerate.
Dispose of used batteries promptly. Keep away from children.
